A complete SEP sesam environment consists of different modules, which can be combined according to your needs to implement optimized backup. Modules interact with one another through SEP APIs which are also used for interaction with another software.

SEP sesam also provides additional modules and functionality that enable consistent backup of databases (Oracle, MS SQL, IBM DB2, Informix SAP R/3, etc.), applications (like SAP), groupware systems, and virtualization environments. Some of these extensions are already a part of a Client package, and some require a separate license in order to function. For details on licenses, see Licensing. Check SEP sesam OS and Database Support Matrix to learn what is supported on which platforms. For list of all supported extensions and their configuration, see Extensions.

Once you have determined how you want to set up your SEP sesam environment, you can install the required components. Note that the installation procedure depends on the platform on which you are installing a SEP sesam package. Also, the procedure for installing different packages might differ.

Microsoft Windows installation

Prerequisites

Before starting the SEP sesam installation, make sure that you are logged in as a local administrator or domain administrator.

For remote access via remote desktop connection (RDC), the RDC administrator needs the same access rights as the local administrator.

To install any of the SEP sesam components (SEP sesam Server, RDS, Client or GUI), you will require an installation file which can be downloaded from Windows download. Make sure to download the correct file for your processor type.

Note

SEP sesam RDS does not have a dedicated installation package. To install RDS, use the SEP sesam Server package.

If you are planning to install a server (including the GUI) or the GUI, Java Runtime Environment (JRE) must be installed on the system. For details on the required Java version, see Java Compatibility Matrix.

The .Net Framework 4 is required for server installation and can be deselected for all other SEP sesam components during installation.

x86 operating systems with more than 3.25 GB RAM must either reduce the amount of RAM to below to 3.25 GB or migrate to an x64 operating system. This is necessary because SEP sesam requires 64 KB blocks for LTO (Linear Tape Open) whereas an x86 system can only write 32 KB blocks to tape drive because the PAE (Physical Address Extension) is automatically activated. Also, a loader cannot be accessed properly by SEP sesam.

SEP sesam uses name resolution for server to client communication. Before installing, you should test DNS name resolution by simply pinging (using both, long and short name) from server to client and back. For details on DNS resolution check, see How to check DNS configuration.

Ensure that any used SCSI devices are recognized by the operating system to which you are installing SEP sesam. SEP sesam checks the SCSI bus attached storage devices during the installation and adds its data to the database. SEP sesam can only see devices recognized by the operating system.

It is recommended to disable firewall to avoid problems during the SEP sesam installation. Once SEP sesam is installed, you can enable the firewall with exceptions made for the SEP sesam services.

Locate the download folder where you saved the SEP sesam installation package and double-click the sesam-srv-<Version_ID>-windows.x<SysType>.exe file to start the installation. Note that on Windows 7, you must explicitly execute the .exe file as administrator even if you are logged in as an administrator. Select your installation language and click Next.

Agree to the license agreement and click Next again.

Choose whether you want the the SEP sesam services to run under the Standard system accountor a Custom user account. It is recommended to give the SEP sesam Server services a Domain user account belonging to the Domain admins and the Local administrators groups. After choosing a user account, click Next.

Select an installation directory for the program files (including the folders <SESAM_ROOT>\bin and <SESAM_ROOT>\skel) and the application data (including the folder <SESAM_ROOT>\var. This folder requires significant storage space if installing a server). Click Next.

In the next window, select which of the four SEP sesam components you want to install (SEP sesam Server, SEP sesam Remote Device, SEP sesam GUI or SEP sesam Client). There is an additional option of installing a GUI with the SEP sesam Remote Device and a client with the SEP sesam GUI.

After selecting a component, click Next.

Note

SEP sesam Server package already includes all other components. If you are installing a Remote Device Server (RDS), you can also include a GUI. If you are installing a GUI, you can also include the Client.

Depending on which components you are installing, proceed accordingly:

If you are installing the SEP sesam Server, click Install and then Finish to complete the installation.

If you are installing the SEP sesam RDS, SEP sesam GUI or SEP sesam Client, type the name of the SEP sesam Server (in the example below, the name of the server is Informatix).

Note

You must enter the hostname and not the IP address of the SEP sesam Server. The server name may not contain underscores.

Click Next. The firewall information dialog is only intended for purposes of information. Take note of the information and click OK. Click Install to install the selected SEP sesam component and then click Finish to complete the installation.

Linux

SEP sesam provides RPM packages for the most common Linux distributions (for example, SuSE and RedHat) and DEB files for Debian Linux distributions. The latter run on most Debian-based distributions, such as Ubuntu. For details on Debian packages, see Debian Repository.

Prerequisites

Before starting the SEP sesam installation, make sure that you are logged in as root.

To install any of the SEP sesam components (SEP sesam Server, RDS, Client or GUI), you will require an installation file which can be downloaded from Linux download. Make sure to download the correct file for your processor type.

SEP sesam uses network resolution for server to client communication. Before installing, you should test DNS name resolution by simply pinging (using both, long and short name) from server to client and back. For details on DNS resolution check, see How to check DNS configuration.

Ensure that any used SCSI devices are recognized by the operating system to which you are installing SEP sesam. SEP sesam checks the SCSI bus attached storage devices during the installation and adds its data to the database. SEP sesam can only see devices recognized by the operating system.

It is recommended to disable firewall to avoid problems during the SEP sesam installation. Once SEP sesam is installed, you can enable the firewall with exceptions made for the SEP sesam services.

On KDE and Gnome, the installation generates a link on the root user desktop to start the GUI. This link must target the correct SEP sesam Server. Open the link properties and add the following parameter to the command line:

AIX

Prerequisites

Before starting the SEP sesam installation, make sure that you are logged in as the root user.

Installing SEP sesam component for AIX (depending on availability either SEP sesam Client or Remote Tape Server can be installed) requires special RPM packages to be installed with the standard RPM package manager (part of the AIX default installation). You can download the required RPM packages from the SEP Download Center and copy them to the AIX system to /tmp/rpm-packages/. Then install the package via RPM:

cd /tmp/rpm-packages/
rpm -i *

SEP sesam GUI requires Java Runtime Environment to be installed on the system. For details on the required Java version, see Java Compatibility Matrix.

SEP sesam Remote Tape Server or Client installation

Download the relevant SEP sesam package from the SEP Download Center and copy it to the /tmp directory on your AIX system. The following example shows the installation of the sesam_rts package. The procedure for installing SEP sesam Client is slightly different; the name of the package is substituted with sesam_cli.

Follow the wizard and select the relevant components that you wish to install, tapeserver or client, respectively:

# ./sm_setup
Found 1 valid archive(s): 'aix_rts.4.4.2.58.tgz,'.
What do you want to install? (tapeserver,client)
tapeserver

Set the installation directory; the recommended place to install sesam is /opt/sesam. Make sure that there is at least 10 GB of free disk space available. Optionally, choose another installation directory that has enough free space:

In which directory do you want to install (If not existing it will be created):
'''/opt/sesam/'''
In which directory do you want to install (Read-Write):
'''/opt/sesam/'''

Specify the SEP sesam Server hostname in your environment; you must provide the DNS hostname of your backup server. The DNS Server must be correctly resolved on the AIX system. For details, see How to check DNS configuration.

To which SEP sesam Server should be connected?
'''backupserver.hostname'''

Once you specify all required information, SEP sesam software installation and configuration is started. If you have problems with starting SEP sesam services, check the Troubleshooting Guide.
